i have just had my UK Accord Type R FI


had the car on the dyno before fitting the turbo nad got 214bhp @ flywheel

just had it done with the turbo fitted and was pushing 246BHP @ flywheel

i was looking at 300BHP.


the tuner told me that i needed to change the cams back to stock as i have high lift cams and it would cause over lap. and there not suited for boost

is this right, could it cause 50BHP loss with my piper VTEC22BP270 cams

 

I think you should be more worried about the 11:1 compression ratio then the cams

 

how much boost are you running?? what are the other mods?? i hope youve built the engine for boost, or else that sucker is gonna blow......and yes, cams COULD cause that much loss, but its probably not the only problem

 

i have just purchased loads of goodies so i can sort the internals

like JE pistons 9:0:1 darton sleeves, eagle rods ect.

the turbo is running 5psi only and thats it no other mods so maybe its the cam set up thats casuing the problem. and i do have skunk2 adjustable pulleys and there really over the + ( advanced ) so im sure its the cams.

anyone else think its the cams

cheers for your help

 

for a turbo application, you don't want too much overlap and i know the accord type r cams are pretty aggressive. i suggest that you pick up some h22a1 cams. what turbo kit are you using?

 

its a drag turbo kit

 

i think with using some either boost friendly cams, or maybe oem h22a cams, plus 6-7 psi, you could easily see 300 whp...good luck buddy...

 

thanks guys

i was just worried that the company was ripping me off and the adivse they told me was rubbish.

bit thats cleared it up
